Flea Bytes: Paracentesis and Bleeding Risk

AASLD Practice Guidelines:

Bleeding from paracentesis is relatively uncommon. The routine use of FFP or platelet transfusion is not recommended before paracentesis. You should avoid any engorged veins as most bleeding occurs from the venous circulation.

It may be reasonable to correct patients who have bled before with paracentesis, have hyperfibrinolysis (as they wouldn’t be able to clot effectively due to factor depletion), patients with evidence of overt bleeding from mucosa (epistaxis, vaginal bleeding, etc), or have history of bleeding at puncture sites (like IVs or blood draws).

Flea Bytes: Differentiating Synthetic Dysfunction from DIC in Liver Disease

You can check factor VIII levels because they tend to be normal to increased in liver disease as it is not produced by the liver, but rather endothelial cells. In DIC all of the factors are consumed, so factor VIII levels will be low.

The other test that maybe helpful is checking a d-dimer. The d-dimer tends to be significantly increased in DIC due to profound fibrinolysis. However, d-dimer levels may also be elevated in liver disease, but usually only mildly elevated.
